LIVERPOOL are facing a goalkeeper shortage for the crucial Premiership run-in after deputy stopper Patrice Luzi was injured for the reserves last night.

With Chris Kirkland still out with a broken wrist, manager Gerard Houllier may have to call-up teenager Paul Harrison as back-up to Jerzy Dudek.

Harrison came off the bench as the reserves won 2-0 at Sunderland and it would be an emotional afternoon if he was understudy against Fulham.

Harrison's Liverpool contract expires at the end of the season and he's been told it won't be renewed.

But Houllier may have no option but to put the 18-year-old on the bench if Luzi's hand injury doesn't respond to treatment. The French keeper, (above), was having an x-ray on his index finger this morning.

Meanwhile, Philippe Mexes' agent Olivier Jouanneaux has told Liverpool they'll have to qualify for the Champions' League to sign the defender.

"It is a key motivation for him to play in the European Cup," the agent said. n Houllier insists Liverpool will have achieved something from the season if they finish fourth.

The manager says it will be a triumph over adversity if the club qualifies for the Champions' League.

"People should not underes timate the importance of fourth place and the reward it can bring," said Houllier.

"Certainly, Liverpool should be aiming higher than that. But in view of the season we have had, and the problems we have encountered, I would consider it a good achievement if we fulfilled our objective."
